Where these two actually differ
- We flag Non-stick coating (lid) degradation and shedding, Seal ring and gasket degradation and Electrical component moisture ingress and mold on the Instant Pot and not on the Zojirushi.
- We flag Stainless steel nickel content and Rubber gasket off-gassing or degradation on the Zojirushi and not on the Instant Pot.
- The Instant Pot is stainless steel inner pot, unspecified non-stick coating on lid where the Zojirushi is Stainless steel inner pot, aluminum outer housing, which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Zojirushi is the one to buy.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
